2 Claims.

The present invention relatesto tobacco smoking pipes and specificallyto pipes designed to separate from the smoke any and all liquidsubstances such as tars, water and other materials distilled from thetobacco, and to likewise trap and remove saliva from contact with thesmoke.

Among the objects of the invention is a tobacco smoking pipeconstruction in which the smoke, in passing from the bowl, is separatedfrom its content of easily condensible material before traveling to thepipe stem proper.

Another object is a construction in which any saliva passing into thestem is bypassed into a chamber out of the path of the smoke enteringthe stem.

Still another object is a pipe having large chambers for collection ofthe substances indicated and so arranged as to be easily and effectivelycleaned.

Other objects will readily occur to those skilled in the art uponreference to the following description and the accompanying drawing inwhich Figure l is a longitudinal central vertical section through a pipeembodying the invention.

Figure 2 is a front end View of the lower portion of the bowl with apart removed.

Figures 3 and 4 are sectional views on line 33 and 4-4 respectively ofFigure 1.

Figure 5 is a section on line 55 of Figure 4.

In the drawing, the pipe is shown as consisting of a bowl Ill, stemportion I I, and the removable bit l2, which latter may be inserted-inthe end of the stem and held in place by friction in the well knownmanner.

The bit l2 will be provided with the usual longitudinal passage l3extending therethrough and with a reduced portion l4 adapted to fitwithin the end of the stem II. It is also provided with a forwardextension consisting of a flattened portion 15 through which extends thepassage l3 and which is provided with a vertical through passage l6intersecting with the passage l3.

The adjacent end of the stem II will be provided with an enlargedopening 20 into which extends the horizontal flattened portion [5 of thebit, and the latter divides the chamber 20 into an upper and lowerportion.

Extending forward Within the stem in the lower portion thereof, is thechamber extension 25 which serves as a space for collecting any salivaor other liquids which may find their way into the chamber 20. From theupper portion of chamber 20 a smok passage 30 leads forward and into theupper part or ceiling of a forward chamber 3|. This chamber ispreferably immediately below the bowl l0 and is enlarged by having itextend lengthwise of the stem II as indicated at 32. The forward portionof chamber 3| is provided with a removable end wall 33 which serves thepurpose of closing the'chamber and also permits easy cleaning of thechamber 3|.

Extending from the'bowl 10 into chamber 3| is a small smoke passage 35so arranged as to direct smoke entering the chamber away from the openend of passage 30.

It will be noted that the two chambers 31 and 20 are very much larger incross sectional area than the passages 35, 30 and I3. The effect of thisis to temporarily slow down the stream of smoke in each of the twochambers. Such slowing down permits a reduction in temperature of thesmoke and likewise gives the entraining vapors a chance to condense anddeposit in the chambers.

As is well known in the burning of tobacco in a smoking pipe, there isconsiderable distillation of tars, water vapor, etc., which if allowedto pass into the smokers mouth, produce disagreeable results. Likewise,there is usually a collection of moisture within the stem due to thecondensation of some of the water vapor mentioned, which is disagreeableto the smoker.

The construction shown and described herein, however, .permits thedeposit of such materials in the chambers 3i and 20 and prevents theirpassing through the bit I2.

I am aware that the invention may be embodied in other specific formswithout departing from the spirit or essential attributes thereof, and Itherefore desire the present embodiment to be considered in all respectsas illustrative and not restrictive; reference being had to the appendedclaims rather than to the foregoing description to indicate the scope ofthe invention.

I claim:

1. In a tobacco smoking pipe having a bowl and stem portion and aseparable bit, a relatively large chamber insaid stem portion beneathsaid bowl and having an extension into said stem, means for conductingsmok downwardly and in a forward direction from said bowl to saidchamber, a smoke conduit leading from the ceiling of said chamber at apoint remote from and to the rear of a vertical line from the smokedischarge of said conducting means, said conduit extending lengthwise ofsaid stem in the upper portion thereof, a second chamber in the bit endof the stem and into which said conduit opens, said second chamberhaving an extension into ward end flattened and provided with a vertical10 through passage intersecting the longitudinal passage, said stemhaving an enlarged opening to receive said flattened end and to bethereby divided into upper and lower chambers, a smoke passage extendinglengthwise of said stem from the said upper chamber to a point adjacentthe lower end of said bowl, a forward chamber below said bowl and intowhich said passage opens downwardly, said forward chamber and said lowerchamber each having an extension in the lower part of said stem andextending lengthwise thereof, a conduit leading from the bowl to saidforward chamber and opening thereinto at a point ahead of the passageopening and inclined so as to direct smoke away from the last mentionedsmoke passage, and removable means constituting one wall oi said forwardchamber.
